Output: I am an Aticleworld Author

Explanation:When we are OR-ing the test( unsigned char variable) with 0x01 and 0x02. The value of test will be 0x03 (because initially test value is 0x00). When we perform the And-ing operatotion on test with 0x01 and 0x02 then expresstion will return non-zero value, for example (0x00000011 & 0x00000001 => 0x00000010).
